Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-bis(chloranyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 2,4-dichloro-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 635698-50-9 A834415.
CATO supplies 2,4-bis(chloranyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 2,4-dichloro-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 635698-50-9 A834415 (CAS 635698-50-9), a certified reference material (molecular formula C8H9Cl2N3, MW 218.08 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-bis(chloranyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 2,4-dichloro-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 635698-50-9 A834415 (C8H9Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,4-bis(chloranyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 2,4-dichloro-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepine 635698-50-9 A834415 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
